/* Names for a dwarf2 debugging section.  The field NORMAL is the normal
   section name (usually from the DWARF standard), while the field COMPRESSED
   is the name of compressed sections.  If your object file format doesn't
   support compressed sections, the field COMPRESSED can be NULL.  Likewise,
   the debugging section is not supported, the field NORMAL can be NULL too.
   It doesn't make sense to have a NULL NORMAL field but a non-NULL COMPRESSED
   field.  */
